The midlayer is already throttling i/o in the places where host_quiesce was trying to prevent further i/o to the device. It's also problematic in that it holds a lock over GFP_KERNEL allocations. Signed-off-by: NDan Williams <dan.j.williams@intel.com>

Some of the chain walks to get back to our dev are invalid. isci_remote_device_change_state: delete rather than adding conditional deref chain walking isci_request_change_state: fix, it was being called too early isci_request_ssp_io_request_get_lun: fix compile breakage hidden by ifdef DEBUG Signed-off-by: NMaciej Trela <maciej.trela@intel.com> Signed-off-by: NDan Williams <dan.j.williams@intel.com>

The lldd actively disallows requests in the "starting" state. Retrying or holding off commands in this state is sub-optimal: 1/ it adds another state check to the fast path 2/ retrying can cause libsas to give up However, isci's ->lldd_dev_found() routine already waits for controller start to complete before allowing further progress. Checking the "starting" state in isci_task_execute_task and the isr is redundant and misleading. Clean this up and introduce a controller-wide event queue to start reeling in "completion" proliferation in the driver. The "stopping" state cleanups are in a similar vein, rely on the the isr and other paths being precluded from occurring rather than implementing state checking logic.
